    • A method for fabricating a workpiece and a laser processing apparatus are provided to prevent a workpiece from being broken by using a laser beam which does not apply an impact to the workpiece. A method for fabricating a workpiece comprises the steps of irradiating a laser beam onto a workpiece(22) to increase the temperature of the workpiece so that at least a part of the workpiece is melt, and maintaining a state, in which the part of the workpiece is melt, until at least a part of the workpiece is separated. The laser beam includes a continuous wave or a pseudo continuous wave. The laser beam includes a pulse wave having a pulse width of 1millisecond or more, and irradiation time of the laser beam is less than the pulse width. While the laser beam is irradiated, temperature is continuously increased until an object to be processed is cut.
    • 提供了一种用于制造工件的方法和激光加工装置,以通过使用不对工件施加冲击的激光束来防止工件被破坏。 一种用于制造工件的方法包括以下步骤:将激光束照射到工件(22)上以增加工件的温度,使得工件的至少一部分熔化,并保持其状态 工件熔化,直到工件的至少一部分被分离。 激光束包括连续波或伪连续波。 激光束包括脉冲宽度为1毫秒以上的脉波,激光束的照射时间小于脉冲宽度。 在照射激光束的同时,持续增加温度,直到切割被处理物体为止。
